The reason I came here with this issue: - Tesla has no mechanism to report a new issue. I took my car into the support system to address this issue and it was a complete waste of time talking to support people who can only repeat what they've been told to say. They told me the only...

Yes, 100% I have an agenda. I would like to replace my Model 3 12v lead acid battery because having to deal with a car failure situation every 3 years when the lithium technology exists at a very low price that prevents this situation from coming up ever again is worth a little effort on my...

I have my old Tesla lead acid battery sitting around and I took a look at the voltage on it and the highest I could get the voltage with the charger is 12.8 volts. So an old battery makes no sense because an old battery would not be able to get anywhere near 14.6 volts.

So you're saying that Tesla would "help" a lead acid battery that was old, by blasting it with a 20 amp load to below 12.6 volts? That would be recipe to force an earlier failure.

Just copied from evseekers.com: Tesla 12v Battery Replacement Cost (Revised Estimate) Even though Tesla does not fully publish the estimated cost to the public, most users have reported paying between $120 and $250 for the Tesla Mobile Service. Some even claimed to have paid up to $70 in extra...

I think California prices are higher than what you are showing. But in any case thats's still $129 million dollars a year revenue for Tesla.

From what I've uncovered the last few days, if the Ohmmu is a lithium ion battery, it would have the same issue as the one I have. The only way to avoid this problem would be if you had some fairly complex electronics that have to be able to maintain 14.6 volts being drawn at 17 amps for a...

OK, with I've learned so far, if I wanted to sue Tesla in a court of law for anti-consumer behavior, I'm sure I would win the case. Here's why I can prove they are actively sabotaging Lithium batteries: After being forced to replace my brand new lithium battery with a Tesla Lead Acid...

In observing what happens with a 12 volt lead acid battery in a Tesla while it is powered on, I could NEVER see it actually using any power from the 12 volt battery. The only thing it does is try to charge it at a gentle 3 amps. What happens with a LITHIUM 12 volt battery is...

Yes, great idea to plug in a 12 volt battery!! See my lengthy post about what happens in this case. Quick summary: absolutely nothing close to what it does with a lithium battery. BTW, the lithium battery I bought cost $120 and if the specs are correct, I should never have to...

If you live in a cold climate, two years is about what you get out of a lead acid battery (roughly speaking).

Being an engineer myself, if I thought about how I would manage energy in system that contained: a) an enormous 85,000 amp hour battery that operates at very high voltage (400 volts) that has huge capacity and can handle huge currents, but has the downside of high capacity...

Meant to say, Explain to me why Tesla should NOT address this issue?

I'm an engineer too, which lots of expertise in electronics and software, so I know enough to recognize stupid software when I see stupid software. Tesla designs their software with the assumption that you always have connectivity and if Tesla denies you power you have an alternative...

I have spent about a week and several hours trying to figure out why a 50 amp hour Lithium Iron Phosphate battery, even when fully charged at install time, gets a low voltage condition and pops up the "12 volt battery must be replaced" error within a few hours of installation, whether you are...
